Who hath believed our report? and to whom is the arm
of the LORD revealed?

Isaiah 53.1

When he shall come to be glorified in his saints, and to be admired
in all them that believe (because our testimony among you was believed) in that day.

2 Thessalonians 1.10

The question posed by Isaiah 53 is answered in its corresponding book, 2 Thessalonians. It is not a KeyLink
because it is quoted in John and Romans, but it is a first order projective link, that also is
particularly intriguing because it is in the form of a Question and answser:

Projective Link: Who has believed our report?

PIsaiah( 53, 1 ) PBible( 53, 1 )

Those who deny our report are implying that we have broken the Ninth Commandment,
"Thou shalt not bear false witness against thy neighbour." This is a strong Spoke 9 theme
which also manifests with perfect clarity in
2 Thessalonians as discussed in Believing Lies and
the opening verse of Romans 9.

The essence of Isaiah 53 is the "cutting off" of Messiah Jesus Christ, as it is written (vs. 8):

He was taken from prison and from judgment: and who shall declare
his generation? for he was cut off out of the land of the living: for the
transgression of my people was he stricken.

This is discussed in context of Spoke 9 of the Bible Wheel in the Obadiah article,
How Thou Art Cut off!. The idea of cutting off, and
its relation to the Covenant, originates in
Genesis 9.
